Knife Sharpening
BED KNIFE SHARPENING
Each bed knife is provided with two cutting edges. When the exposed edges become blunt, the knives can be
turned over and repositioned to present the new cutting edges.
It is not necessary to grind bed knives to the closely matched tolerance of the rotor knives and as with the rotor
knives, small nicks in the cutting edges will not seriously affect knife cutting efficiency. Bed knives smaller
than the minimum dimension shown must be replaced along with their fasteners.
It is important to note that the minimum dimensions given for the rotor knife and bed knife cannot be
combined simultaneously to produce a cutting combination. The grinding charts shown below and on the
previous page indicate the rotor knife and bed knife combinations that will work for each type of rotor knife.
**EXAMPLE: A 55° land rotor knife
with a 3.937 inch " A " dimension will work only with bed knives
having an "E" dimension of .940 or more.
*NOTE: Replacement knife sets and knife re-sharpening services are available from STERLING.
